摘要

年龄估计在人类识别中起着至关重要的作用。在位于整个骨骼骨架的众多年龄标记物中,髂骨的耳廓表面呈现出弹性结构,目前有不同的耳廓年龄估计方法。在这些方法中,Osborne方法被认为通过使用稳健的年龄类别和离散相位描述符来实现准确的年龄估计。本研究旨在通过对耳廓表面的计算机断层扫描(CT)检查来评估奥斯本方法在印度人群中的适用性,这一方面目前尚未报道。为了做到这一点,收集了380人的CT扫描,并使用Osborne方法进行了评估。基于CT的检查表明,Osborne描述的表面纹理很难通过3D CT图像来欣赏。与某些特征相关联的不明确的定义,以及每个阶段内特征的马赛克显示,进一步阻碍了该方法的有效应用。使用该方法,男性和女性的总体准确率分别为99.47%和98.90%,相应的不准确值分别为10.10年和9.04年。在最初的研究中,使用替代的、更稳健的年龄段,获得了显著降低的准确率百分比,这表明与该方法相关的可靠性有限。每十年计算的不准确度和偏差值表明该方法在40-59岁老年人中的相对效用。本研究中遇到的低准确率、高错误率和不同的方法障碍表明,奥斯本方法在印度人口老龄化中的适用性有限。

Applicability of the six-phase method for auricular age estimation in an Indian population: A CT-based study.

Age estimation plays a crucial role in human identification. Amongst numerous age markers located throughout the skeletal framework, the auricular surface of the ilium presents as a resilient structure, with different methods for auricular age estimation currently in practice. Amongst these methods, the Osborne method is believed to permit accurate age estimation through its use of robust age categories and discrete phase descriptors. The present study aimed to assess the applicability of the Osborne method in an Indian population through a computed tomographic (CT) examination of the auricular surface, an aspect presently unreported. In order to do so, CT scans of 380 individuals were collected and evaluated using the Osborne method. A CT-based examination indicated that surface texture described by Osborne is difficult to appreciate through 3D CT images. Indistinct definitions associated with certain features, and the mosaic display of features within each phase further prevents applying the method effectively. Overall accuracy percentages of 99.47% and 98.90% were obtained using the method in males and females, respectively, with corresponding inaccuracy values of 10.10 years and 9.04 years. Significantly reduced accuracy percentages were obtained with alternate, more robust age brackets presented within the original study, demonstrating the limited reliability associated with the method. Inaccuracy and bias values computed for each decade indicate the relative utility of the method in aging 40-59-year-old individuals. Low accuracy percentages, high error rates and different methodological hindrances encountered within the present study illustrate the limited applicability of the Osborne method in aging an Indian population.
